From Amy Ruck   15 March [1872]1

Pantlludw, Machynlleth.

March 15th.

Dear Mr. Darwin

I am very sorry that I am unable to tell you anything about the ledges, as hitherto we have failed to discover any appearance of what you describe— The steep slopes here are perfectly smooth, & it is difficult to imagine any change taking place in them, as worm-casting are rarely to be seen on the hills.2

Thanking you for your letter I am | Your’s sincerely | Amy Ruck

The year is established by the relationship between this letter and the letter to Amy Ruck, 24 February [1872].
CD had asked for a drawing of ledges that might have been formed by the washing down of worm-castings (see letter to Amy Ruck, 24 February [1872]).


Has failed to discover the signs of earthworm activity that CD described.
